Ender 3 60mm Fan Mainboard Cover

thingiverse

Ender 3 mainboard cover for 60x60x25mm fans. Avoids the wire connectors on BigTreeTech SKR Mini E3 V2.0, the Y-axis carriage wheels, and bed leveling screws. The fan recess is filleted for strength. I opted to not integrate a fan grill design to avoid blocking the air way or creating noise from turbulence. You will need to be neat with your wire management inside the case to avoid the wires slipping into the fan blades. Generally the sides of the fan will keep the wires from slipping under it, but I added zip ties around them to keep at the sides of the case. Depending on your settings changing infill will result in very little difference in print time or actual infill since most dimensions are only 2mm to 3mm. I used 50%, but as low as 20% would be fine. Use regular thread forming fan screws that come with most retail fans to mount this. The screw holes are countersunk for them to sit flush.
